efficiency assumptions when comparing fuel costs

Depends. Kids eat lunch at school, wife usually skips breakfast & eats lunch at work.

Don't think we're that un-ordinary - seems our dishwasher can hold quite a few dishes.

I don't think we're the only ones around here that only spend that much on DHW via electric - have reads lots of similar postings.

Here's another fuel comparison calculator for you:

On wood stove efficiency, I doubt you'll find any real numbers as efficiency varies much depending on installation, burning methods and wood seasoning. I think the #s I've seen on woodheat.org are at least 60% for modern stoves and likely close to 70% for many.

We do a dishwasher load about every 3 days for 3 persons. It takes that long to get a decent load of dishes. Most pots and pans are hand washed. Even when there were 4 of us we showered less, usually every other day unless doing heavy dirty work.
